An old neighbor asked me to remove a wood pile from her home. She said it had been cut, split and stacked about 6 or 7 years ago. She thought some was a locust tree, which got my interest. I've hauled away about half a cord of obviously well seasoned, but very solid wood. While there was some black locust, there is also another tree I can't ID. I attached pics of the bark and grain. Any ideas?
